 Topic: Need PTO Wood Chipper Advice for D17
Posted: 27 Sep 2022 at 9:33am |
We got a fairly heavy (5" max) PTO used wood chipper I will be running on the D17IV. We don't plan to compete with Asplungh or anything clearing telephone lines, but will use it occasionally for wood chips for the garden, etc. No Fargo stuff either hopefully. It is an older one made by Pequea Machine in New Holland, PA. It is well built, but I notice it doesn't have any kind of overrun clutch or anything. Everything is direct with the PTO. So once that massive flywheel gets moving, it will be moving for a while, and I'm not too crazy about having that thing directly through the PTO.
I'm thinking I would buy an override PTO clutch and use that to help decouple the chipper from the PTO. Has anyone had any experience with a chipper like this, and would a regular PTO override device help?

When you want to shut it down, push in the foot clutch and pull the PTO lever out of gear.

I run a 3" chipper on my D15. When you put your foot on the clutch, it comes to a stop pretty quickly. I don't think you should need an over running clutch in this case. They are more handy for mowers while you are moving.

I'd at least put a shear bolt or friction clutch on it. If the irresistible force meets the immoveable object, its the drive line that will take the brunt of it!

I have a Woodland Mills 6 inch chipper on a D17 without overrunning clutch. The machine has a shear bolt, but never sheared. Works great and the tractor doesn't even know it's back there!

Unless you plan on driving the tractor with it running, you shouldn't need an over running clutch. Those don't offer any sheer protection anyway. I'd assume the chipper has a slip clutch or sheer bolt. Just make sure that setup is in god condition.
